## Discrepancy

DURING PREFLIGHT CHECK THE EMERGENCY LIGHTS AT ROWS 23 THROUGH 32 EXTINGUISHED WHEN THE EMERGENCY LIGHTS WERE SELECTED ON.  WHEN THE EMERGENCY LIGHTS WERE SELECTED OFF THE EMERGENCY ESCAPE PATH LIGHTING CAME ON INTERMITTENTLY.  MAINTENANCE REPLACED THE EMERGENCY LIGHT CONTROL PANEL ON THE OVER HEAD PANEL AND THE EMERGENCY LIGHT POWER SUPPLY, ALL OPERATIONS CHECKED GOOD.
